About the DPI Calculator
The DPI Calculator is a free, private tool that runs entirely in your browser — your inputs never leave your device, and the answer appears the instant you enter them.
Screen decisions — size, resolution, pixel density and viewing distance — shape how comfortable a phone, laptop or TV is to use. This DPI Calculator computes one of these display figures so you choose the right device.
The calculation applies the standard display metrics: resolution in pixels, aspect ratio, pixel density (PPI), and the viewing distances recommended for TVs and monitors.
For TV buyers in Pakistan, the size-to-distance relationship matters most: a 55-inch TV needs a viewing distance of roughly 2–3 metres. Sitting too close to a large screen, or too far from a small one, ruins the experience.
Pixel density (PPI) explains why a small phone screen looks sharp while a large TV at the same resolution looks soft. This calculator makes those comparisons concrete.
